This must seem little a total novice question. I'm working on learning scales, and for those that involve dropping to lower strings (ex. Eb Major on the 2nd string, 1st fret) I'm having trouble muting open strings. For example, in the scale mentioned above, I can move Eb F G Ab Bb C D Eb no problem. The problem occurs when I go in reverse. Starting on the 3rd string, 6th fret I'll go Eb D C Bb Ab G - this is where the problem occurs. When I go from the open G to F, I have trouble keeping the open G from ringing out. This occurs with other similar scales as well. So...should I be using right or left hand techniques to mute that G when I'm done?
